To a'Zl'who-m it may concern: v

Be it known that I,. ANroN BIRNBAUM, a

citizen of the United States, residing at Erie,

in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Rollers for Barrel-Scrubbers,

new or substitute ring.

. section.

of which the following is a specification.

This invention relates to a roller for barrel scrubbers for imparting rotation to barrels during the scrubbing operation.

Heretofore rollers for barrel scrubbers have'been constructed with outer frictional rings projected outwardly a considerable distance beyond inclosing flanges and preferably constructed from rubber, rubber compounds, or other suitable material. These outer frictional rings are made continuous and by constant action in connection with barrels become worn and cut by being crowded down on the flanges and have to be replaced. It has been necessary in rollers as'heretofore constructed to disengage the roller'from the o crating shaft to replace a worn outer ring y a new'one or to remove the shaft from its bearings in order to dis' engage the ring from theshaftand apply a The object of the resent invention is to overcome these disa vantages by forming a roller for barrel scrubbers with an'outer' ring which is readily removable both from the roller and the shaft without requiring the latter to-bedisengaged from its bearings and also to permit the application of. a new ring without disturbing t e operative association of the shaft with relation to its supporting and driving elements.

The invention consists in the construction suitable supporting bearings 2 and having a driving wheel or gear. 3 as s own, though it is obvious that this driving Wheel may be modified at will. On the shaft 1 between the'supporting bearings 2 barrel rotating. rollers 4 are mounted in proper spaced relation, two of these rollers being shown in the present instance. Each roller comprises a hub 5 which is keyed to the shaft 1' in any suitable manner. The hub 5 rigidly carries a rim 6 having a fixed flange 7, and removably applied against the rim is a disk or ring 8 constituting a removable flange and forming with the flange 7 a circumferential seat to re movably receive an outer frictional ring 9 formed ofrubbe'r, rubber compound or any other material adapted .forthe purpose and having an outer beveled edge 10 to form a bearing surface for the barrel and to conform in a general way to the'longitudinal curvature of a barrel body. The disk or ring 8 is held in removable relation to the rim 6 by bolts or nuts 11 arranged' zit-intervals as shown. The essential feature of the invention resides in the outer frictional ring 9 and consists in forming said ring with a lap j oint' 12, which in the present instance is shown straight with respect to the length of the roller in relation to each terminal of the latter for a greater portion of the length of'the joint so that when the two terminals of the ring produced by cuttin the same are joined there will be a flush over ap. When the ring I 9 is inserted in the circumferential seat against the rim 6 and flange 7, and the'disk or ring 8 is tightened up against therim, the joint of the said ring will be firmly held .by the frictional pressure of the disk or ring 8 acting against the resistance of the flange 7.

In ap lying the improved outer frictional ring 9, t e disk or ring 8 is loosened or disen gaged from the rim 6 and the saidlringis opened and fitted against the circumferential seat or the rim 6 and flange 7 without requiring dissociation of the shaft 1 from its bearings or a removal of the roller as a whole from the shaft After the ring is applied the disk 8 is tightened up and the roller is ready for service. Should, the ring 9 become worn and unfit for use, it may be readily removed from the roller and replaced by a new ring without disturbing the mounting of the shaft 1 or the parts 006 crating with the latter.

The readya p lcation andremoval of the outer frictiona ring 9 as just explained saves considerable time, and annoyance, particularly where a large number of scrubbing machines is used and requires repair-in the manner specified. The rlng embodyin the fea-" tures of the invention may be readily ap lied and removed by one'person in view 0 the fact that disconnection of the shaft carrying the roller on Which the ring is mounted or operates is unnecessary. ln-the preparation of the ring 9 for use as a part of the roller, it will be observed that it isonly necessary to cut through'the body of the ringto provide the lap joint 12 and no complex operation is necessary, as forinstance moldin or seetioning and joining and it is possible to utilize stock already found in the market or to cut the rings from-a rubber cylinder and by a simple subsequent operation bevel the same and form the lap joint entirely throu h the ring from the inner to the outer perip cry. The lap joint extending as shown in relation to the ring is very effectively secured by clamping the disk 8 thereagainst and thusconfining the joint between said disk 8 and the flange 7 no other securing means beingnecessary, as the compression of thedisk 8' will result in a practical retention of the extremities of the ring provided by the formationof the joint against movement either radially or laterally and by loosening the disk 8 it is obvious that the ring 9 may be readily separated from the roller.

What is claimedis:

A rollerfor a barrel scrubbing machine comprising a hub carrying a rim with a fixed 'removably applied to the side of the rim opposite that from which the fixed flange prop ects, and a solid rubber ring-having an outer beveled periphery and'applied around the rim and held between the fixed flan e and disk and removable from the rol er by loosenin the disk, the ring beingcut in a straight line centrally thereof fully through from'the inner-to the outer periphery and then at right angles in opposite directions to reverse faces of the ring from the'terminals ofthe first cut to form \41 normally loose lap joint, the ring being separable from the rim by moving the one cut extremity thereof laterally with relation to the other, the ring being compressed between theilange and the disk when the latter is secured to the rim and the lap joint also compressed and retained intact solely by the disk tightly forcing the same against the fixed flange.
